TDA8444

Octuple 6Bit DACs with I2C-bus

GENERAL DESCRIPTION

The interface circuit is a bipolar IC in a DIP16, SO16, or SO20 package made in an I2L-compatible 18 V process.

The contains eight programmable 6-bit DAC outputs, an I2C-bus slave receiver with three two for SO16 programmable address bits and one input VMAX to set the maximum output voltage. Each DAC can be programmed separately by a 6-bit word to 64 values, but VMAXdetermines the maximum output voltage for all DACs. The resolution will be approximately 1⁄64VMAX.

FEATURES

• Eight DACs with 6-bit resolution

• Adjustable common output swing

• Push-pull outputs

• Outputs short-circuit protected

• Three programmable slave address bits

• Large supply voltage range

• Low temperature coefficient.
